Build AI Agents with Codex + Postman

Build AI agents with Codex while Postman handles the APIs behind them. With the new Postman plugin for Codex, you can discover the APIs you need, create OpenAPI specs and Postman Collections, add test coverage and mocks, and manage your APIs throughout the development process - all without leaving your Codex workflow. In this demo, we use Codex and Postman to build a working learning agent from scratch, connect it to real APIs, test it, and get it ready to ship. Learn how the Postman plugin can bring API discovery, management, testing, and best practices directly into your agent-building workflow.
